TO ALL WHOM, IT MAY CONCERNE` l V Beit known ,that l', W. H. H'NKINSO'N,of the city,'county, and Stato of NewYork, have invented certain"`-- newand 4useful improvements ih Machines for Beating and Cleaning Carpets;and I do `hereby declare 4that the vfollowing is a full, clear,and-exactdescrption'of the saine, reference being had to theaccompanying drawings,

making'a portion ofthis specification, in whieh v I Figure 1 is avertical longitudinal section of a machine constructed according tomyinvention.` Figure 2, a plan or t'op view of the same. F i Similarletters of reference indicate corresponding parts in both gures.

This invention consist-s' in certain novel arrangements of parts,whereby carpets, or other fabrics of like,` p

character, of anylength or thickness, may be thoroughly cleansed fromdirt or dust bythe action of rotating brushes andbrooms and by theoperation of tlexible beaters, without injury to the said fabricsandivith` avery moderate expenditure of time.

To enable others to understandfthe construction and operation of myinvention, willproceed to describe .it with reference to the drawings. vp i The working parts of the machine are supported by a streng frameworkof any suitable construction, and

, which in the drawingis marked A. Situated 'at the forwardend of thisframework aretwo horizontal feeds,

rollers, B, which are situated one over the other. Placed at therearmostend of the framework ,ncarly or quite on a level with therollers B, is another pairof'similar feed-rollers, C4. The shaft of theupper roller of each pair works in bearings, which are placed inVsuitable vertical guidesformed upon tlicframeworkA, in order thatnthesaid u ppfer rollersmay befr-ee torisqand, fall, Mand thus adjustthemselves to carpets'of `diiferentthickness or to'any variation in thethickness of the carpet. vSituatedut the inner sideo'f thewplowermostone of cach pair of rollers B and C, parallel therewith and with itsupper side, nearly or quite on a level with the` upper side thereof, isa bar, D; and stretched or extended from one of these-bars D to theother are o series of strong horizontal cordsME, which serve to supporta portion of the weight of the carpet,` as will be hereinafter` fullyset forth. Located in rear of the pair of rollers B, and just back of:thelbar D, adjacent .to-the said rollers, are two transversecylindrical brushes, F, 'which are situated one above and the otherbelow the-supporting cords. E, and which, having a rotary movementcommunicated to them by means hereinafter described, act upon thetwo`side's of the carpet as it is passed through the machine to 'brushand clean the saute. Situated transversely over the supporting cords Eis a horizontal shaft, G, which hasarranged spirally thereon anumber ofciiexible beaters," al, which may consist of pieces of rope of the properlength, and which blyrbeatng upon the' carpet as it passes to thebrushes F, assist materially in expelling the dust and dirt therefrom.VSituated atvthe rear-most end of the framework A, below and in rear ofthe feed-rollers C, is a transverse rotating shaft, I,.whil 1 1 isfurnished 'with radial arms, a, towliich are attached longitudinal bars,b, the said arms and bars constituting i a kind of frame; and securedup'on these bars 6,'at suitable distances apart, and in'a positionradialto the shaft I, are any number of stili' brushes, c, which may bemade of broom-compr other suitably stil material, and

which, in the operation of the machine, are designed to brush the innerside or surface of the carp et.-V The means by whichthe requiredmovements are communicated Ato the several parts areas` follows: Thedriving- AShaft l is furnished with a driving-pulley, d, andhas formedupon it-a Worm ortangenbscrew, e, which gears' into the pinion j', uponthe rear extremity ofrtlie -secondary shaft K, which is furnished withtwo bevel gearwheels7 g and h, of which the wheel g gears into a pinion,z', `upon the extremity of the shaft. of the lowermost'` roller B, whilethe other wheel h gears in like manner into a similarrpinion, k, uponthe shixftof therlovvermot,

one of the other pair of rollers C. The mechanism by which, ineaeh .pairof rollers B and C, motion is coins,4 municated from the lower to theupper one thereof, is identical, the shaft of the lower rollcrineachcase beingprovided atene end with a small `spur-wheel, shown indotted lines'at m, in,g.1and having pivoted,at;one end thereto a curvedlink, n, the upper end of which is connected with the shaft of theupperroller byfstraight` link, r. 'lhe' said .shaft of the upper rolleris furnished with a spurfwheel, shown in'dotted linesnt ,in g.`, 1; andpivotcd within the links nr, are two intermediate spur-gears, 1t v, oflikeV character, these'spur-lwheels '111,38, u, v, gearing together, andthc joint between the links n r permitting the upper roller to rise inordbrto adjust4 itself to any thickness-of `carpet or fabric, or -to anyinequalities in the thicknessthereof, without'bingng th` cylindricalbrushes F, substantially as h erein set forth for the purpose specified.

aforesaid lsplir-v'vheels out of' gear with each other. -L shows a shortshaft placed at rghta'ngles to the secondary shaft K, and connectedtherewith by twf'ibevel-genrs,l w w', and furnished at the, innerend'witlna small spurwheel, u', which gears into one of the gears bywhich the shaft of the lower-most ono of the cylindrical brushes F isconnected wthrtheshaft 'of the upper one thereof, the two shafts of thesaid brushes being geared together inthe same manner aswthe two rollersoi' 'each 'pair oi' fcedngrollers, as hereinbfeforosctfnrthgthe shaft ofthe upperrnost of the brushes Fworking in vertically slidingbearings in'the same manner asithe shafts of the uppermost feeding-rollershereinbeforc described,.s`o' that the. aforesaid uppermost brush mayrest lightly upon the carpet during the operation of l cleaning the`same. '.llhe` shaft Gr, carrying the beaters a*, is rotated bye.

belt aeting'upon the band-wheel Zr at the end thereof. v In usingthe'inachine, the carpet or other fabric, of any desired length, and'of'a width not exceeding the 4length of the feeding-rollers, has one ofits ends'iirst passed'hetweenthe two feeding-rollerait'thefront of themachineand then, backv between the cylindrical brushes F, andro'ver thesupportingeords E, thence, between the two rearmost feed-rollers, andoverpthe rotary frame which carriesy the stili' brushes c, and downward'over thevtransverse supplementary roller c*, from .whchi't is carried'forward underneath the parts just mentioned,'and is joinedby sewing tothe other Aend 4offthe ea-rpet,`-so'that the said carpctforms a kind of'endless apron. -Motion being given to the machine bythe Ineansherainbefore describe'dpthe carp-et is drawn back by the feed-rollers,and the cylindrical brushes F, rotating in a. direction contrary to'that inwhich the carpet is drawn, .act upon the sides thereof, and.brush the dust and"dirt from'the surfaces of the same. The ilexiblcheaters rv", as the carpet passes along, striking or beating upon, thesame with a force proportionedto the velocity of the shaft G to whichthey are attached, lexpel the dust and dirt from the 'interstices'of thecarpet,

thecarpet being sustained against the said blows by resting upontlie'supporting cords E.' At' lthe same tinie the stiff brushes c,acting-upon the inner surface of theA carpet, still further remove.thedust -and.dirtt-herefrom. The carpet yis thus carried around until,having several` times passed through the machine, or, in other wordsbeen subjected to the brushing' and beating actinof the parte justmentioned, 'has become thoroughly cleaned,

whereupon the two ends thereof are discpnneeted and it is withdrawn fromthe machine. The uppermost roller of 'each pair 'of feeding-rollers, andalso the uppermost ofthe cylindrical brushes being capable of movingA ivertically, and boing thus selfadjusting to the thickness of the carpetor other v i fabric, it follows that the-machine is adapted tocleaningcarpets of 'any desired thickness without any chalnge being' made in themachine.` It is designed that the greater portion of -the,machine besuspended within asuitah'le dust-room or casing, in such 4 manner thatthe dust' from the carpetma-y not" escape in front of the'machine.-

, What I. claim as new, and desire to secure by Letters Patent, is

l 1. The two pair of feeding-rollors 'B and C, and the cylindrical brushFfmade self-adjusting as described and arranged in relation with eachother and withthe l'supporting cords E, and flexible heaters a*,substantially as herein setl forth for the purpose. specifiedf 2. Thestiil` brushes c, arranged upon a rotating frame, in combination withthe vfeedingrolers B C, and
